[Samba] Samba 4 dns-resolv-prob with different subnets

[L.P.H. van Belle]

Grusse..

adviced is your hosts to put the fqdn first like this. 
>on dc-01:
>127.0.0.1   localhost   localhost.localdomain
>192.168.0.101 dc-01.obel.lan	dc-01
>
>on dc-02:
>127.0.0.1   localhost   localhost.localdomain
>192.168.1.100 dc-02.obel.lan dc-02

>> /etc/resolv.conf
>
>on dc-02 192.168.1.100 (dns-resolution works):
>search obel.lan
>nameserver 192.168.1.100
>
>on dc-01 192.168.0.101 (dns-resolution doesn´t work):
>search obel.lan
>#nameserver 192.168.0.100   # put the # infront first while testing. 
>nameserver 192.168.1.101

then ping the fqdn to each other of one fails, post it here. 
remove the # from the /etc/hosts. on DC2 and test again. 

Is DC1 a new installed and/or was it installed and removed at first? 
Is there any firewall 

Can you run this on both servers. 

host -t A dc-01.obel.lan
host -t A dc-02.obel.lan
... 

now i saw you other thread.
"Samba 4 fsmo-handling on crashed dc-server" 
is your DC1 a new installed server inplace of an other "old DC1" 
than i suggest you first do all check on the DC2. 
make sure all FSMO roles are there. 
make sure your dns is correct there and ALL old records are gone. 
go through the wiki as you would do a new install, perform all check standing there.
